To all whom it may concern:

Be it known that I, WILLARD Ln GRAND BUNDY, of Binghamton, in the county of Broome and State of New York, have invented a certain new and useful Calculating-Machine, of which the following is a specification.

My invention has for. its object the pro duction of a calculating machine, which is particularly simple in construction and efficient in operation; and to this end, it consists in thecombination, construction and arrangement of the component parts of a calculating machine, as hereinafter fully described and pointed out in the claims.

Figs. 30 and 31 are sectional views taken, respectively, on line 30 30 and 3131, Fig. 1. Fig. 32 is an edge view of a portion of the lower part of one of the recording members. Fig. 33 is a sectional view taken on line 3333, Fig. 32. Fig. 31 is a detail view of a modified means for conelevation of a modified means for connecthe illustrated embodiment of my invention comprises a frame, a keyboard, an actubers, and multiplying, calculating and printing mechanisms. It will be understood, however, that one or more of said parts may be dispensed with, if desired.

The frame A is of any suitable form, size and construction, bein here shown, Figs. 1 and 2. as provided wit front and side walls a, a a and a top a said side walls having lateral extensions a formed with upwardly proiccting arms a,

The keyboard B may also beof any desirable form, size and construction, and is here illustrated as consisting of a plurality of necting the keys andihe movable parts or. levers cooperating therewith. Fig.. is aningr the recording and controlling members.-

' ating part, recording and controlling mems keys I) b movable vertically in the front portion of the top a of the frame A. Said keys I) are arranged in a plurality of series, and with the exception of the front key of the lefthand series are normally elevated by spring 6 As best'seen in Figs. 3, 1 and 5, the upper ends of the keys of each series of the keys I) are arranged one above the other from the front to the rear of the keyboard; and as best seen in Fig. 1', the keys I) b are disposed at the outer sides of the lefthand and righthand series of keys I). It is obvious, however, that my invention is not limited to the particular arrangement of keys shown and described. Said front key of the lefthand series of keys is termed. ditto key, is provided with a plurality of shoulders, is held in either its elevated or depressed positions by a yieldin'gstop b Fig. 18, fixed to the frame A and detachably engaging the shoulders of said key, and is forced to its different positions by hand. The remaining keys of thelefthand series'of keys I; are usually provided with, and distinguished by, suitable words, asnotes, checks, drafts, etc. Allof the keys b, w ith the exception of said ditto key, are hel'din position by locking membersb", the locking members for each series of keys being fixed to a common shaft or rod 6. As clearly shown in Figs. 14 and 15,,each of the keys I) cooperatingwith a locking member 6 is provided-with separated shoulders 6 6 which respectively engage arms; 6 b projecting from the corresponding looking member 6 at opposite sides of the shaft or rod b forming the pivot for said locking m'ember, said arms 6 being normally in position to be engaged by the shoulders 6 Fig. 14. Vhen one of the keys Z) is depressed to its operative position, the lower shoulder b thereof encounters: the upper surface of thelower arm 6 of the corresponding locking member 72 and forces the lowersurface ofthe arm b of said locking member into engagement withthe top face of the upper shoulder bf of said key. as seen in Fig, 15. At the same time, the top surfaces of the upper arms I) of the. locking memb ersfor the remaining keys of the series of keys including said depressed key', are engaged with, the lower faces of the upper shoulders. Z)? of said keys, thus preventing downward movement of any additional key of said series. I

As best seen in Figs. 12 and 13', the locking members Z) ofeacli series, areheldin theirinoperative and operative positions by springs b which are mounted, respectively, on supports Z2 each f'having one end pivotally supported on the frame of the keyboard and its other end pivoted to an arm bf fixed to the correspondlng shaft Z). the pivot for uniting the contiguous ends of said support and arm being movable on ope posite sides of a line drawn through the axes of the corresponding shaft 12 and the supportb. As the actuating part C reaches the limit of its motion, the locking members I) are all forced to their normal or inoperative position by means, here shown, Figs. 19, and 21, as consisting of a pair of sliding bars I) I) arranged at an angle with each other and a lever 6 connecting said bars for transmitting motion from one to the other. The bar 6 carries a series of shoulders 12, Figs. 12 and 13, for engaging shoulders I)" on the arms I), and the bar 6 Figs. 1 and 2, is extended through the front wall a of the frame and provided with a. suitable hand-piece. Thecentral portion of the bar I), Fig. 19, is. formed with a depending shoulder 6 which is engaged by an arm c,on the actuating part G when reaching the limit of 0, Figs. 1, 2, 3, 4, 5,

The actuating part 19, 20 and 21, preferably moves relatively to the keys B andthe-ineans for limiting the. movementof the controlling members,

and consists. of a shaft 0, arms 0 c 0 c, a

drum 0 and a hand-piece c. The shaft '0 is journaled in the side wallsa a of the frame A; the arms a c c 0 project substantially radially from the shaft 0; the drum 0 is formed With a substantially smooth peripheral face and with a lateral shoulder 0 Fig. 3, and the hand-piece 0 F igs. 1 and 2, is provided with a longitudinally-yielding shoulder a which encounters a stop or shoulder a on the frame A for limiting the movement of the actuating part at each complete operation or rotation thereof, and is movable laterally out of engagement with the stop orshoulder a, for permitting the actuating part to commence an additional operation or rotation. Retrograde movement of the actuating part is prevented by a pivoted stop-pawl 0 Fig. 3, engaging the substantially smooth peripheral face of the drum 0.

As illustrated in Figs. 1, 3, 4, 5 and 16, the recording members D consist of rocking parts having their upper portions arranged in close proximity and their intermediate and lower portions separated. Said recordingimembers are pivoted on a shaft (1, are held in their normal position by the controlling members E, and are drawn to their predetermined position by independentlyoperating springs d. The upper face of eachof the recording members D is provided with two series of indicating charactersd (Z Fig. 17, the series 61 registering witlran observation-opening a? in the frame A, and the other series (Z registering with the portions of the record-sheet forreceiving the predetermined impression or record.

The controlling members E, Figs 3, i, 5, 6 and 7 govern the setting of therecording members D and as usually constructed, consist of longitudinally reciprocating bars. Corresponding ends of the controlling members are pivotally supported and are provided with gear-teeth normally meshing with similar teeth on the lower faces on parts of the recording members D. The opposite ends of the controlling members E cofiperate with means for preventing movement of the controlling members from their normal position, means for limiting the movement of said members, and means for returning the members E to their normal position.

Asgenerally constructed, the means for holding the controlling members E in their normal position consists of fixed stops e and rocking levers c, Fig. 3. The' stops 6 normally enter notches e in the loweredges of the controlling members E, and when the controlling members are withdrawn from their normal position, the stops 6 engage the pUrtions of said lower edges in front of ches 6 and elevate the front ends of the controlling members thus moving said front ends in a plane disposed at substantially right angles with the plane of the longitudinal movement of said controlling members. The rocking levers 0 hold the controlling members E in their normal position in engagement with the stops 6, are forced from their normal position by independently operating power transmitting devices a, and with the exception of the righthand lever e, are each provided with an arm 6*, which projects laterally from the right hand side thereof and rocks the adjacent lever e from its normal position when it is desired to have the recording member corresponding to said adjacent lever print a cipher at the righthand of a digit. Said righthand lever e is provided with an arm 6, Figs. 6 and 7 projecting from its lefthand side for engaging the next adjacent lever 6 when it is desired to print a cipher at the lefthand of a digit. Each power-transmitting device (2 consists of a rocking section 6' normally engaged with one of the levers e, loosely mounted on a shaft e, and held in its normal posi tion by a spring 6, a second rocking section 6 fixed to the shaft 8", and having its axis substantially coincident with that of the section a, a connection 6 between the sections e e for locking said sections together, and a spring (2 for automatically forcing the connection e into its operative position. Said connection e is here illustrated as an arm pivoted, Fig. 11, to the section 6 and provided with a tooth, Figs. 9 and 10, movable laterally into engagement with a corresponding tooth on the section a but it is obvious that any other desirable connection may be used to transmit motion from the section 6 of said power-transmitting device. The sha-ft e is provided with a suitable arm o operated by the arm 0 of the actuating part C.

The means for limiting the movement of the controlling members E is here shown as consisting of movable parts or levers e 6 between the keys and the controlling members E movable relatively to the controlling members into a plurality of positions, one lever e being provided for each series of keys, and one lever 6 for each controlling member. Each movable part or lever o is pivoted at one end of the corresponding series of keys, and is provided with a substantially horizontal forwardly-extending arm a arranged directly beneath the lower ends of said series of keys and with a rear depending toothed arm 6. each movable part or lever o at one end of the corresponding series of keys, the lower ends of the keys codperating with said movable part or lever are unequally separated from the pivot of the part or lever e and, consequently, uniform depression of the keys will rock said part or lever unequal distances-on its pivot relatively to the corresponding controlling member. The front ends of the arms 6 of the movable parts or levers e normally rest against rearwardly extending arms of the connections 6 as seen in Fig.6, for forcing said connections from their operative position, and holding the teeth thereon out of engagement with the teeth of the sections 6 and as soon as one of the movable parts or levers e is rocked from its normal position, the spring 6 of the corresponding powertransmitting device 6 forces into its operative position in engagement with the section 6* of said device the connection e previously held out of operative position by the front end of said movable part or lever.

As best seen in Figs. 3, 4 and 5, the lower ends of' the keys codperating with the parts or levers e are formed with any desirable means, as catches 6 which arenormally arranged in their inoperative position out of engagement with the arms a and serve to connect a key, when depressed, to the arm a of the corresponding movable part or lever e. In the preferable construction of my invention, the catches 6 are pivoted to the lower ends of the keys 6, are forced to their operative position by springs 6 are normally rocked from their operative position by engagement with the bar a; through which the lower ends of the keys '6 are guided, andare provided with shoulders for detachably engaging laterally- By pivoting Ill) projecting shoulders on the movable parts or levers a By connecting the depressed key to the corresponding movable lever or part c, it is possible to return said part or lever to its normal position when, for any reason, the operator decides to elevate said key by moving the sliding bar 6 reartial y horizontal forwardly-extending arm a and with a rear upwardly-extending toothed arm e normally engaged with the toothed arm a of the .corresponding movable part or lever 0 The front end of the arm of each movable part or lever 6. cooperates with a series ofshoulderse which are provided on the corresponding controlling member E. are arranged in steps one below and in advance of the other, and are also arranged in front of .the pivot for said lever 0 when the controlling member is in its normal position. Said front ends of the arms 0 are normally separated from the lower and rear or advance shoulders of the controlling members for permitting the controlling members, when released, to make a single. advance, whereupon the further movement thereof. will be restrained by the arms 6. This single advance of one of the controlling members E will be permitted when the rocking lever e for holding thesame in its locked position is forced from operative position by the engagement with said rocking lever of the lateral arm (9* provided on the next adjacent rocking lever to the left. At the same time, and without depression of any of thekeys in the corresponding series of keys, all of the controlling members E to the right of said one of the controlling members will be similarly released and will make a single advance. Upon the first advance of any of the controlling members, the corresponding recording members will be moved so as to aline the ciphers thereon with the observation-opening a and the printing point. It will be understood. that u 011 the movement of the' righthand lever 0', controlled by the depression of one of the corresponding series of keys, the arm e projecting from the lefthand side of said lever will actuate the next adjacent lever e whereupon the corresponding controlling member will make a single advance. In case one of the keys of a series of keys is depressed, the movement of the part or lever 6 effected by the depression of said key, as pr viously described, elevates the front end of the arm 0 of the part or lever e cooperating therewith relatively to the controlling members and alines said front end with the shoulder e corresponding to the depressed key, and, consequently, the predetermined characters of'the corresponding recording member are alined with the observation-opening a and the printing pdint, when said controlling member is released and is drawn rearwardly relatively to the parts or levers e? e by the spring cl until its further rearward movement is limited by said part or lever e In order to secure exact alinement with the printing point of the predetermined characters on the recording members D, I usually provide my invention with means for moving the controlling members E into their operative position after the same have set the recording members in the predetermined positions and just before the printing takes place. This means is here illustrated, Figs. 3, 4 and 5, asv pivoted pawls e fixed to a rock-shaft e, and having corresponding ends movable into engagement with teeth on the intermediate portions of the controlling members E, and a lever having one end connected to one of the pawls and its other end arranged in the path of the arm 0 of the actuating member C.

As best seen in Figs. 3, 4 and 5, the means for returning the members E to their normal position, consists of the arms 0 of the actuating member C, which are arranged one in advance of the other from the left to the right for returning the controlling members successively, and are provided at their lower faces with gear-teeth for engaging teethe upon the controlling members E. When the controlling members E are in their normal position, the arms 0 swing above the teeth 6 without engaging therewith, but after said controlling members have been moved from their normal position and their front ends have been elevated by the sto s e the arms 0 o erativel en a 'e which controls the transmission of power from the actuating part (3 to the means for forcing from their operative position the locking members 7)? for the keys I), and prevents the transmission of power from said actuating part to the locking members until after the actuating part has made a predetermined number of complete rotations .or operations suflicient to force the locking members from their operative position. As here illustrated, the multiplying mechanism consists of a spring F, a rotary wheel f, a spring f, and an escapement- 1. The spring F tends to elevate the sliding bar or plunger Z2 above its position assumed when about to be operated by the arm 0 of the actuating part C, and when said sliding bar orplunger 7) is elevated by the spring F, Fig. 21. the actuating part C revolves with- .out reciprocating said bar or plunger and As best seen in Fig. 1 the wheel f is .alined with an opening 0. in the top a of the frame A, and is provided on its periphery with a plurality ofcharacters, as the cipher and the numerals 1 to 14, inclusive, although the exact number of numerals is immaterial. Said wheel f is movable by hand in one direction and is also provided with a laterally-projecting arm f which, as shown in Fig. 19, normally holds the sliding bar or plunger 6 in its position assumed when about to be operated by the actuating part C. The spring f returns the wheel f to its normal position, and the escapement f causes the return movement of the wheel f by the spring f to take place step by step. Said escapement is actuated by a cam f on the actuating part G. hen the wheeel f is set so that its cipher is alined with the central portion of the opening a or other predetermined starting point for the wheel f, the arm f holds the sliding bar or plunger b in its normal position, and said bar or plunger is operated by the actuating part C as said actuating part reaches the limit of each complete rotation or operation. If the wheel f is moved ,so

that the character or numeral 2 is alined with the starting point of said wheel, the arm f is elevated two steps above the normal position of the sliding bar or plunger I), the spring F elevates said bar or plum-1' ger, and the actuating part-C makes one complete revolution without actuating the bar or plunger b Consequently, the keys previously depressed remain in position to effect a second record in accordance therewith upon the next movement of the actuating part. During the first rotation. of the actuating part, the cam f operates the escapement f and causes the wheel to make a single advance step, and during the second rotation of the actuating part, the cam f again operates the escapement f whereupon the wheel f makes a second step, and its arm f moves the sliding bar or plunger 5" into its normal position. Consequently, as the actuating part reaches the limit of its second rotation or complete operation, the armc' operates the sliding bar or plunger 6 for forcing the lockingmembers b from their operative position and releasing the keys previously held depressed thereby.

In order that the operationvof my multiplying mechanism may be clearly understood, suppose that it is desired to multiply 222 by 34: The units, tens and hundreds keys 2 are depressed and the wheel f is set so that the numeral 4 is at the starting point of said wheel; the actuating art C is operated, and as the same comp etes the limit of its fourth rotation or operation, the keys reviously depressed are elevated; the tens, hundreds and thousands keys ,2 are then depressed and the wheel f is set so that the numeral 3 is in the position formerly occupied by the numeral 4, whereupon the actuating part is operated, and as the same reaches the limit of its third operation, the keys last depressed are elevated. The number 222 will then be multiplied by 34, as will be obvious to those skilled in the art.

The calculating mechanism, Figs. 3, 4, 5, 19, 20 and 23 to 29 inclusive, as generally constructed, consists of a carriage g, means for moving the carriage laterally, calculating members g, and means for effecting and controlling the return of said calculating members to their normal osition. The carriage g is of any suitab e form, size and construction, and is movable laterally on guides a a, Figs. 3, 4, 5, 28 and 29, by any desirable means, Figs. 19, 20 and 23, consisting preferably of-a rock-shaft g having one end provided with a cam g for engaging,

and forcing the carriage laterally and its other end suitably connected to the key 6. A spring g,- Fig. 24, forces the carriage g to its normal position, and upon the depression of the key 6, Fig. 23, the rock-shaft g and its cam 9, Figs. 19, 20 and 23, move the carriage g to the right against the action of the spring The key I) which 1 term the total key is connected to all the movable parts or levers e except-the lefthand part or lever e for forcing said parts 6 from their normal position when the key I) is depressed, and is also connected to the sliding bar or plunger 6 in order that when said bar or plunger is operated by hand or by the actuating part G, the key 6 may be raised to its normal position.

As here illustrated, the connections between the key b' and all of the movable parts or levers 6 except the lef-thand part or lever e consists of a rock-shaft 7", Fig. 19, and a'link g connecting said rock-shaft to the key Z). The rock-shaft g is provided with a flattened portion which rests upon the upper edges of the movable parts or levers e, Figs. 3 and 4, cooperating therewith in close proximity to the pivots therefor, and rocks said parts or levers for simultaneously elevating the front ends of the corresponding movable parts or levers a above the uppermost shoulders e of the controlling members E, in order that when the key Z) is depressed, the means for limiting the movement of the corresponding controlling members E may be out of operative osition. I prevent the movement of the lef thand part or lever e by providing its upper edge with a cutout 6, indicated by dotted lines Fig. 4, which receives the flattened portion of the rock-shaft 9 By preventing the movement of the lefthand part or lever e by the key b I can operate said part or lever b any of the corresponding or lefthamd. series of keys except the ditto key whenever it is desired to record the words notes, checks, drafts, etc in connection with the number or total accumulated by the calculating mechanism. The connections between the key 1') and the sliding bar or plunger 5 generally consist of a lever 57', Fig. 19, having an arm connected to the key I) and a second arm depending into the path of a shoulder 6 on the bar or plunger 6.

When the key I) has been depiressed, the

rearward movement of the sli ng bar or lun er I) efiected either by hand or bythe rotation of the actuating part C engages the shoulder b with the depending arm ofthe, lever g and thus rocks the leverg and elevates said key to its normal position.

The calculating members 9' are here shown as wheels, Fig. 26, loosely' mounted on a shaft g and each provided with opposite substantially similar parts or halves g each formed with a plurality of shoulders g which are arranged one in advance of the other at unequal distances from the shaft g", areinoved successively into position to be engaged by a shoulder e upon the corresponding contrblling member E, are normally out of alinement with said shoulder 6, Fig. 28, and are disposed in alinement therewith when the carriage g has been shifted to the right, Fig. 29. One calculating member g is preferably provided for each controlling member E except the lefthand member E, each of the calculating members g is formed with opposite shoulders g", Fig. 26, and each of said members g except the lefthand one is provided with additional opposite shoulders g Figs. 26, 28 and 29. The outer ost shoulder g of each of the similar parts or halves of said calculating members 9 may be termed space shoulder, the next adjacent shoulder Zero shoulder, and; the remaining shoulders successively '1 '9 shoulders. Said space and zero shoulders of each similar part or half of one of the calculating members 9 are bothprovided upon a portion 'of the periphery of-the calculatingmembenequal-ing the amount of said pe-.

riphery advanced by a single step of the calculating member, and during ts complete revolution said calculating member "makes twenty steps or advances. The shoulders 9 cooperate with cam-shaped shoulders e Fig.3 upon the rear ends of'the, controlling members E,- -"are reciprocally movable through the calculating members 9 and are, connected to flat Springs 9 which permit said shoulders to yield laterally if engaged.

by the cont-rolling members when returning to their normal position.

As here illustrated, Fig. 4, the means for rotating the calculating members g consists of pinions g and levers 9, one pinion and one lever being provided for each of the cal-- culating members. The pinions 9 are connected to the calculating members g so as to permit said pinions to rotate rearwardly without transmitting motion to the calculating members and to cause said pinions to advance the calculating members when returning or moving forwardly. The connections between the pinions 9 and the calculating members 9 are here shown as ratchet-wheels g, Fig. 4, secured to the pinions, and the pawls g secured to the calculating'members and engaging the wheels g. Said pinions g are rotated by the toothed surfaces or parts of the recording members, are normally disengaged from said surfaces, and are normally arranged in position to be engaged by the recording members. In order that the recording members may engage with the pinions 9' without any liability of their toothed surfaces or parts binding upon the pinions and not properly registering therewith, the teeth 03 of said surfaces nearest the pinions 9 are free to yield from said pinions and are prevented from yielding in the opposite direction, Figs. 4, 32 and 33.-

The levers g are pivoted to the carriage, are held in their normal position by springs g and are provided with fixed shoulders 9 and'each of said levers except thelast two at the left is provided with a yielding straining the pawls from assuming their op-' erative position. Corresponding ends of the springs 9 are fixed to the calculating members 9 and their opposite ends are fixed to drums frictionally connected to the shaft 9 by springs g and capable of rotation on the shaft 9 against the action of said springs g. The springs 9 return the calculating members 9" to their normal position with corresponding shoulders g thereof in engagement with the upper faces of the shoulders g of the levers g. Said calculating members are returned to their normal position whenever the desired total amount has been calculated or accumulated and upon the return of said members they are in their initialposition to commence an additional calculation.

The pawls 9 normally engage ratchetwheels provided on the calculating member's .g'- and prevent retrograde movement of said members 9'. The means for operating the pawls 9 generally consists of springs the same from their operative position, and is also provided with an arm 9 Figs. 3 and 2%, having a lateral extension or shoulder Said arm 9 is usually operated by a reciprocating bar Fig. 3, having one end arranged in the path of the shoulder c of the actuating part C, and its other end provided with an upwardly extending arm 9 Figs. 3 and 24, which is normally out of alinement with the shoulder 9 and is movable into engagement with said shoulder 9* when the carria e g has been moved laterally by the depression of the key 6. It is sometimes desirable to prevent the actuating part C from moving the reciprocating bar 9 and forcing the pawls g from their operative position when the operator wishes to know or record the total amount accumulated but intends to add thereto. I accomplish this result by suitable means which connects the front end of the bar 9 to the key If, and is here shown, Fig. 3, as consisting ofa lever 9 having one end connected to the bar 9 and its other end connected to the key 6 When the key I) is depressed, the lever 9 elevates the front end of the bar 9 out of the path of the shoulder a, and thus prevents the actuating part C from forcing the pawls g from their operative position.

As best seen in Fig. 3, the means for temporarily restraining the pawls g from assuming their operative position preferably consists of a lever g having a substantially hook-shaped arm for engaging a shoulder 9 of the arm g and holding said arm 9 in its position assumed when rocking the pawls g out of operative position. The lever g is connected by a link 9 with an arm provided on the shaft '6", and, consequently, at the commencement of the operation of the actuating part C, said link (1 rocks the lever g from its normal position, whereupon the'pawls g are immediately drawn into their operative position by the springs 9 The operation of my calculating mechanism is as follows z After the keys. b are set for a predetermined number, say, 20, and the actuating part C commences its operation the controlling members cooperating with the units and tens series of keys are actuated, as previously described, to move the corresponding recording members, so that the number 20 will be set up and printed. In effecting this movement, the controlling member cooperating with the units series of keys, makes a single advance, and the next adjacent controlling member makes three advances. The singie advance of the first controlling member moves the correspondingrecording member into position to engage the pinion g cooperating therewith, but as this controlling member makes no additional advance or step, no movement of said: pinion and the calculating member 9.

rotated thereby takes place. Upon the movement of the controlling member corresponding tothe tens series of keys, the pin-v ion 9 next to the left of the former pinion is rotated rearwardly two steps. As the actuating part C completes its operation or set up or recorded. When the keys I) are again setfor a predetermined number, say 30, a similar operation of the controlling and recording members, previously operated, takes place, and as the recording member which formerly advanced its corresponding calculating member two steps is returning to its normal position after the second operation thereof, it advances said calculating member three steps.

Let it be supposed that it is now desired to set up and print the total amount of 50 accumulated by the calculating mechanism. Theftotal key Z2 is depressed forcing the carriage g'laterally to the right, and moving from operative position all but the lefthand one of each of the movable parts or levers 6 a, for limiting the movement of the corresponding controlling members E. As

said parts a are forced fromftheir normal position, the springs 6 move the. connections 6 of the corresponding power-trans mitting devices 6 into their operative position, and upon the commencement of the movement of the actuating part C, all but the lefthand one of the controlling members E are released and the corresponding springs d immediately move said controlling members rearwardly into engagement with the calculating members cooperating therewith. All of the controlling members to the left of the controlling member cooperating with the tens series of keys will engage their shoulders a with the space shoulders of the corresponding calculating members, and consequently, said controlling members will not operate the corresponding recording members to set up or aline any of the characters thereof with the printing point. The controlling member E cooperating with the tens series of keys 6 will engage its shoulder c with the 5 shoulder of the calculating member cooperating therewith, and, consequently, the corresponding recording member will be set to 5. At the commencement of the movement of the latter controlling member its shoulder 6 will engage the shoulder g of the calculating member cooperating with the controlling member next to the right of said moving controlling member, and will advance said calculating member a part of its first step so that its zero shoulder will be alined with the shoulder 6 of the correcalculating members g, except the two at .the lefthand,-reaches the limit of a half revolution, one of its shoulders g engages the under face of the shoulder g on the lever 9 next to the left, and elevates said lever a limited distance for advancing a single tooth the calculating member 9 next to the left. After the shoulder g" has passed beyond the shoulder g, the spring 9" returns the lever g, and the pawl 9 yields freely to permit the return of said lever.

The printing mechanism, Figs. 1,2, 3 and 30 preferably consists of a support H for a record-sheet, means for moving the sup port toward and away from the recording members D, and means for feeding the record-sheet and the inking ribbon. Said support H is of any desirable form, size and construction, is movable lengthwise of separated shafts h h, .Figs. 1, 2 and 3, which are secured in the arms a. and form guides for said support and is pivoted on the shaft h. Themovement of the support H along the shafts h k may be limited by a lever 72?,

Figs. 1 and30, pivoted to the support Hand movable into annular grooves k in the shaft h. As here illustrated, the means for moving the support H toward and away from the recording members D consists of the shaft h and means for operating the same.

Said shaft h is eccentrically journaled,

Fig. 3, in the arms (1* and serves to move the corresponding portion of the support H toward and away from the contiguous part of the frame A,.t hus moving the printing point of said support toward and away from the-characters of the recording members D registered with said printing point. The

shaft hf is operated by a segmental wheel h fixed thereto and a reversely-moving segment h meshing with the wheel 72; and p1voted at 71. The lower end of the reverselymoving segment h is connected toa spring 72. for rocking said part in one dlIGOtlOIL against a stop 71 andis provided with a shoulder it and with a rearwardly-extending arm having a vertically-adjustable shoulder 72.. Said part h cooperates withand is normally disengaged from a catch it which is pivoted at its front end to a lever 72. and is connected to a spring h for forcing upwardly the free engaging end ofthe catch. The lever h is held in its normal position by a shoulder 12 on the frame A, and is connected to a spring 9 of greater strength than the spring k As the actuating part moves from its operative position the shoulderc rocks thelever h and moves the catch h" forwardly into engagement with the shoulder k Immediately after the recording members D have assumed their predetermined position, the shoulder 0 passes out of engagement with the lever h whereupon the spring. it connected theretomoves the part or segment 72. in one direction against the action of the spring h, and by rotating the eccentric shaft it brings the printin point of the support H into position to e set the printing of the record thereon from the characters registered with said printing point. After the record is printed, the shoulder h of the part or segment h encounters the catch It and rocks the same out of engagement with the shoulder h", whereupon the spring 72. reversely moves the part orsegment k and returns the support H to its normal position.

e means for feeding the record-sheet is of any desirable form, size and construction, being here shown as a ratchet-wheel h, Fig. 3, fixed to a roller forming part of the support H and engaging the record-sheet for feeding the same, a pawl h engaging said ratchet-wheel, an arm it which supports the pawl h, is keyed to the shaft 72,,

,shaft 71. and connected to the reciprocating bar 9. The inking ribbon-feed may also be of any suitable form, size and construction, and is here shown as a ratchet-wheel k connected to one of the rollers for said -to the corresponding recording member D by a link d. These are, however, only two of many modifications of m invention which will be obvious to those s illed in the.

art.
